The ARRL Antenna Book

The 'ARRL Antenna Book' is a source of current antenna theory and a wealth of practical how-to construction projects. Use this book to discover even the most basic antenna designs - wire and loop antennas, verticals, and Yagis - and for advanced antenna theory and applications. Many of the antennas in this edition benefit directly from advances in sophisticated computer modeling. This 21st edition has been revised to include information you can use to build highly optimized or specialized antennas. The book includes new content on Near Vertical Incidence Skywave (NVIS) techniques, phased arrays, S-parameters as used in modern vector network analyzers (VNA), Beverage receiving antennas, mobile 'screwdriver' antennas, ionospheric area-coverage maps, and more.
